Power Supply:
The ADJ Flat Par QA12XS contains a automatic volt-
age switch, which will auto sense the voltage when it is plugged into
the power source. With this switch there is no need to worry about the
correct power voltage, this unit can be plugged in anywhere.
DMX-512:
DMX is short for Digital Multiplex. This is a universal pro-
tocol used as a form of communication between intelligent fixtures
and controllers. A DMX controller sends DMX data instructions from
the controller to the fixture. DMX data is sent as serial data that trav-
els from fixture to fixture via the DATA “IN” and DATA “OUT” XLR ter-
minals located on all DMX fixtures (most controllers only have a DATA
“OUT” terminal).
DMX Linking:
DMX is a language allowing all makes and models of
different manufactures to be linked together and operate from a single
controller, as long as all fixtures and the controller are DMX compli-
ant. To ensure proper DMX data transmission, when using several
DMX fixtures try to use the shortest cable path possible. The order
in which fixtures are connected in a DMX line does not influence the
DMX addressing. For example; a fixture assigned a DMX address of 1
may be placed anywhere in a DMX line, at the beginning, at the end,
or anywhere in the middle. When a fixture is assigned a DMX address
of 1, the DMX controller knows to send DATA assigned to address 1
to that unit, no matter where it is located in the DMX chain.
Data Cable (DMX Cable) Requirements (For DMX Operation):
The Flat Par QA12XS can be controlled via DMX-512 protocol. The Flat
Par QA12XS has 8 DMX channel modes, please see pages 9-10 for the
different DMX modes. The DMX address is set on the back panel of
the Flat Par QA12XS. Your unit and your DMX
controller require a standard 3-pin XLR connec-
tor for data input and data output (Figure 1). We
recommend Accu-Cable DMX cables. If you are
making your own cables, be sure to use standard
110-120 Ohm shielded cable (This cable may be
purchased at almost all pro lighting stores). Your
cables should be made with a male and female
XLR connector on either end of the cable. Also
remember that DMX cable must be daisy chained
and cannot be split.

Flat Par QA12XS Cleaning
Listed below are a few common problems the user may encounter,
with solutions.
Unit not responding to DMX:
1. Check that the DMX cables are connected properly and are
wired correctly (pin 3 is “hot”; on some other DMX devices
pin 2 may be ‘hot’). Also, check that all cables are connected
to the right connectors; it does matter which way the inputs
and outputs are connected.
Unit does not respond to sound:
1. Quiet or high pitched sounds will not activate the unit.
2. Make sure that Sound Active mode is activated.
Due to fog residue, smoke, and dust cleaning the internal and exter-
nal optical lenses must be carried out periodically to optimize light
output.
1. Use normal glass cleaner and a soft cloth to wipe down the
outside casing.
2. Clean the external optics with glass cleaner and a soft cloth
every 20 days.
3. Always be sure to dry all parts completely before plugging
the unit back in.
Cleaning frequency depends on the environment in which the fixture
operates (i.e. smoke, fog residue, dust, dew).
Flat Par QA12XS Fuse Replacement
Disconnect the unit from its power source. Remove the power cord
from the unit. Once the cord has been removed, you will find that the
fuse holder is located inside the power socket. Insert a flat-head screw
driver into the power socket and gently pry out the fuse holder. Remove
the bad fuse and replace with a new one. The fuse holder also has a
holder for a spare fuse.
